Application filed September 16, 1919. Serial No. 324,098.

To all whom it may concern:

Be it known that I, ARTHUR W. SIMMONS, a citizen of the United States, residing at Tyler, in the county of Smith and State of Texas, have invented certain new and useful Improvements in Locomotive Driving- Boxes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improve ments in locomotive driving boxes, which is so designed as to eliminate the necessity of removing the driving wheels from underneath a locomotive when necessary to renew crown brasses, and also eliminates the moss sity of removing the driving box from as sembled position on the locomotive when necessary to take up lateral wear, by removing a flange hub liner and applying the desired amount of metal thereto, and it is also an object of the invention to provide a novel and improved device of this general character wherein is eliminated the necessity of expensive machine work and using it in the rough as it comes from the foundry, for at taining the advantages claimed.

In my prior Patent, No. 1,289,562, dated December 31, 1918, I have illustrated, de-

scribed and claimed a device of the character under consideration which has proven satisfactory, and it is a particular object of the present invention to improve upon the type of device illustrated in said patent, whereby to obtain even greater efficiency and more satisfactory results.

Another object of the invention is to provide a device of this general character with novel and improved means whereby the lubricating cellar can be anchored on the hub side of the box.

Furthermore, it is an object of the invention to provide a device of this general-character embodying a sectional flange hub plate and wherein novel and improved means are provided for maintaining the sections of said plate in applied or working position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved locomotive driving box whereby certain important advantages are attained and the device rendered simpler, less expenslve, and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, in which F gure 1 is a view in front elevation of a driving box constructed in accordance with an embodiment of my invention, one of the sections of the hub plate being swung outwardly.

Fig. 9 is an enlarged sectional view taken substantially on the line 9-9 of Fig. 2.

Fig. 10 is a sectional view taken substantially on the line 1010 of Fig. 9.

As disclosed in the accompanying drawings, my improved box comprises an arch 1 and the walls or side members 2. The opposed faces of the walls or side members 2 adjacent the arch 1 are provided with the transversely disposed shoulders 3 which afford supports for the crown brass 4:. The upper face of the arch 1 at substantially the transverse center thereof is provided with the pockets 5 to receive a locomotive spring saddle as is now'generall'y em loyed and said upper'faceof the archl is also provided with a well 6 to contain a suitable lubricant. Each of the outer faces of the walls or side members 2 is provided with the lubricating grooves 7 in communication with the well 6 through the ports 8. The arch 1 has also disposed therethrough the ports 9 leading from the well 6 and registering with the ports 9 of the crown brass so that the contacting face of the crown brass may be suitably lubricated.

Fitting between the lower end portions of the walls or side members 2 of the box is a lubricating cellar C which has one end portion anchored to said walls or side members by a pin 10 extending through an open ing 11 in the cellar C and through an opening 12 in the lower portion of each of the walls or side members 2. The opposite end portion of the cellar C is provided in its side walls and adjacent the top thereof with an inwardly and downwardly inclined, open slot or recess 14 which is adapted to receive a lug 15 whereby a further supporting means is provided for the cellar C. The lugs 15 are preferably arranged adj acent the outer or hub face of the box and in applying the cellar the same is engaged with the lugs 15 before the pin or rod 10 is applied.

The hub faces of the arch 1 and the walls or side members 2 are flat and unobstructed, except for the Vertically disposed and outstanding T-head 16 arranged at the central portion of the arch 1.

The hub liner comprises two sections 17 substantially in duplicate, and the outer side marginal portion of each of said sections is provided with a flange 18. The lower end portion of the flange 18 is continued by a transversely disposed block pocket 19 extending across the adjacent portion of the section 17 while the upper portion of the flange 18 is provided with a lug 20 extending partially along the upper portion of the section 17. The lug 20 is tapered two ways, and has its inner face a inclined downwardly and inwardly for coaction with the lug face 6 provided at an end portion of the wallof the box, these being so tapered as to cause the flange hub plate to fit close against the wall of the box and tighten when bolt 30 is so adjusted.

In applying a section 17, the lug 20 is first engaged with the upper portion of the arch 1, and with said lug serving as a fulcrum, the lower end portion of the section 17 is swung inwardly so that the block pocket underlies a shoulder 21, which is inclined upwardly and inwardly in a direction transverse of the wall or side member, while the upper face 23 of the block pocket is inclined upwardly and inwardly.

The inner edge of the upper portion of the section 17 is provided, longitudinally thereof with a groove or channel 24: which engages a side portion or flange of the T- head 16 whereby the upper portion of the section 17 in conjunction with the lug 20 is effectively held in applied position.

The upper part of the block pocket 19 is provided with the pocket 25 in which is mounted a block 26, and the upper face of the block pocket 25 and block 26 is inof the section 17 is provided with an opening 29 communicating with the pocket 25 and through which extends a bolt 30 threaded through the nut 27. The upper or inner end of the bolt 30 engages with the lower face of the block 26 so that upon requisite rotation of the bolt 30, the block 26 is forced upwardly into engagement with the shoulder 21, whereby the lower portion of the section 17 is effectively locked in working position upon the box.

On account ofthe use of the block 26, it is not necessary that the shoulder 21 be machined, nor is it necessary that the working face of the block be machined, as bolt 30 can be operated to adjust the bolt to compensate) for any inequalities of wear. When it is desired to apply a section 17, bolt 30 is removed and the nut 27 forced into the opening 28 to permit the block 26 to drop to its lowermost position and to a position whereby no obstruction is offered to the requisite swinging movement of the section 17 The opposed faces of the flange 18 of each of the sections 17 and the adjacent face of the wall or member 2 are provided with elongated grooves or recesses 31, each substantially semi-circular in cross section, and which grooves or recesses are in register when the section 17 is in applied position upon the box. 32 denotes an elongated,

, cylindrical bar or filler of a length less than the length of the recesses or grooves 31, and which bar or filler 32 seats within such recesses or grooves to provide further means for maintaining the section 17 in. applied position. The lower end of the bar or filler 32 is beveled, as at 33, to seat within an undercut or dove-tail 34. in the wall at the lower end of the recess or groove 31 in the wall or member '2, whereby said bar or filler is maintained in desired position while the section 17 is being applied.

By having the bar or filler 32- of a length less than the recess or grooves 31, provision is made for the desired relative longitudinal movement of the section 17 and the box when the section 17 is being pulled down to effect the desired engagement of the section with the box.

The inner vertical margins of the outer faces of the walls or side members 2 of the box are also provided with the outstanding solid flanges 35. The flanges 18 and 35 coact with the pedestal in a conventional manner, and the opposed faces 36 of said flanges 18 and 35 are longitudinally curved or rounded so that in practice the box is capable of limited lateral movement, and it is preferred that the faces 36 of the flanges 18 be curved or rounded more than the opposed faces of the flanges 35 thereby materially relieving the flanges 18 of the strain. This lateral movement servesto compensate for the vertical movement of the driving wheel occasioned by a low or high joint in a track, and also materially relieves the top and bottom portions of the flanges 18 and 35 from the strain occasioned by such high and low joints.

From the foregoing description, it is thought to be obvious that a locomotive driving box constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
